Essential Questions:
Why do the words on my shirt read backwards in a mirror?
I can do an 180° on my skate board, but my friend wants me to do a 360°; what will that look like?
Why do I have trouble seeing when I first leave the movie theater?
Big Ideas:
Interpret transformations in the real world.
Unit 5 instruction is focused on the following power standards:
8.G.A.1 Verify experimentally the properties of rotations, reflections, and translations:
8.G.A.1.A Lines are taken to lines, and line segments to line segments of the same length.
8.G.A.1.B Angles are taken to angles of the same measure.
8.G.A.1.C Parallel lines are taken to parallel lines.
8.G.A.2 Understand that a twodimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.
8.G.A.3 Describe the effect of dilations, translations, rotations, and reflections on twodimensional figures using coordinates.
Unit 5 instruction will be supported by the following standards:
8.G.A.4 Understand that a twodimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar twodimensional figures, describe a sequence that exhibits the similarity between them.
